Food Webs



 The Royal Albatross/ Toroa are at the top of its food chain.  It is a very dominant bird mainly due to the size of it and how it spends half of its life at sea. Even though plankton is at the bottom of the web without them the Royal Albatross would die out because if you take out anything from the food web it will kill all of the animals involved. An example of this is if you take out fish from the Albatross’s food web above the plankton would overgrow and the Royal Albatross will die out.

If the Royal Albatross/ Toroa was threatened then the squid would over populate. Because with the size of a Royal Albatross they need to eat a lot, so that makes the population stay the same. If the squid over populate that would the mean they need more big fish and they will run out then the squid will die out. Once the bigger fish are gone that would make the smaller fish over populate. So over all the whole food web would be destroyed and all of that was left would be billions of overgrown plankton.
